storchak [24]

Answer:

c 20

Step-by-step explanation:

You make 53 a day plus 3.75 per sale

Income = 53+ 3.75 s

You want to make at least 128

128 ≤ 53+ 3.75 s

Subtract 53 from each side

128 -53 ≤ 53-53 +3.75s

75≤ 3.75s

Divide by 3.75 on each side

75/3.75≤ 3.75s/3.75

20 ≤ s

You must make at least 20 sales

Diving 5 feets deeper = descent = negative 5 Feets

Each time instrument is checked = (60/3) = depth of 20 feets

Number of times instrument is checked = 3

Hence, maximum depth :

Diving 5 feets deeper * Each time instrument is checked = depth of 20 feets * Number of times instrument is checked

(-5) * (20) * (3) = - 60
